It will also be noted that the universal connection 31 for the shafting30 and .32 is disposed directly above the pivotal connection of theimplement or harvester thresher to the tractor draw bar. In the housing33 the shaft32 carries a gear meshing with a worm gear on a shaft 36,which shaft carries a hand control wheel 37 whereby operation of thehand wheel by the operator on the tractor platform will turn theshafting 32 and 30 by the gearing in the housing 33, as will beunderstood. The gearing is of the conventional worm type and has notbeen illustrated, as it is not thought that this will be necessarybecause of the ob viousness of such construction.

It will be noted that the Z-bar 16 is pierced by a rod 38, which isbolted to the bar 15, as

. shown at 39 in Figure 2. The forward end of this rod 38 is connectedby a vertical link 40 to a crank arm 41 made'fast on the shaft 30. Thetractor platform also carries an operators seat 42, the same having beenillustrated in dotted lines in Figure 2, so as not to obscure the fullline parts therebeneath.

In operation, it can now be seen, that as the outfit travels through thefield the harvester thresher can be raised or lowered in conformancewith the length of grain encountered, by

the operator on the tractor, who need merely turn the hand wheel 37 toturn the shafting 32 and 30, which will either pull up or push down onthe bar 38 depending upon the direction of rotation of the hand wheel37, as

' will be understood. As the platform is raised or lowered, the feederhousing 24 will rise or fall with it and slide over the platform, be

cause of its independent. pivotal connection on. the shaft 23. Thepivotal connection of the cover 25, as shown, will prevent any bindingof this part, as it too will slide over the top of the housing 24. Theuniversal knuckle connection 31 permits of fixing the control wheel 37on the tractor platformin such a position that it will always bedisposed forwardly of and the same relative distance from the operatorsseat 42, regardless of the angular trailingpositon which the harvesterthresher may assume, as when turning corners in the field. This is avery desirable feature and overcomes the difliculties encountered withlever controls mounted on the draft connections'between a tractor and adrawn implement, because when suchan outfit makes turns in the field,these lever controls swing with the implement and do not keep the sameposition relative ,to ,the position of the operator on the tractor.Furthermore, with the control ahead of him for the purpose of steering astraight course. In such cases Where it has 4 been attempted to overcomethe necessity of an operator having to turn around to operate controllevers, such as by lengthening the control levers, it was found thatwhen the outfit makes a sharp turn in the field the levers in swingingwith the implement would forcefully eject the operator from his seat,which is not only objectionable, but highly dangerous. All of thesedisadvantages have been effectively overcome by the novel control andoperating connections disclosed in this application.

It is to be understood that only an illustrative embodiment of thisinvention has been shown and described and that the same is obviouslycapable of changes, such for example as the substitution of a hand leverfor the wheel 37 which could be geared up in a simple manner to rotatesuch shaftin as that indicated by the numerals 32 and 30 1n thisspecification. It is the intention in this application to cover all suchchanges as fall w thin the spirit and scope of this invention asindicated in the appended claims.

What we claim is:
